The effects of brushite coating extract with strontium on the osteoblast-related factor expression of MC3T3-E1 cells / 实用口腔医学杂志

ABSTRACT

Objective:To study the effects of brushite coating with strontium on the osteoblast-related factor expression of MC3T3-E1 cells.Methods:Brushite coating on tinanium surface was prepared by electrochemical deposition and the extract of the coating with stronium at 0.1%,0.5% and 1% were prepared respectively.MC3T3-E1 cells were cultured with the extracts,cell prolifera-tion,ALP activity,bFGF and VEGF mRNA were examined by MTT assay,ALP staining and RT-PCR respectively.Results:Stronti-um containing extracts promoted the proliferation,increased the ALP activity and mRNA expression of bFGF and VEGF(P <0.05)of MC3T3 cells.Conclusion:Brushite extract containing strontium may promote osteogenic function of MC3T3-E1 cells.
